S'r'rn IMPROVEMENT IN AXLE-GAGES.

Specification forming part of Letters Patent No. 115,778, dated June 6,1871.

I, HENRY W. SPAULDING, of the town of Chelsea, countg of Orange andState of Ven mont, have invented certain Improvements in OarriageAxleAdjusters, which, for economy of construction and reliability for thepurpose intended, are believed to be superior to those now in use.

In the drawing, Figure 1 represents a perspective view of the improvedadjuster, and Fig. 2 shows an end view of the standard A.

A,B,and0 are three standards, of T-shape, fastened to the top of theslides D E F, which slide on the horizontal bar G. In said slides areset-screws H I K, intended to operate against said bar to keep eachslide, with its T-standard, in the desired position on said bar. Thestandard A, belonging 'to the slide D, is different in plan ofconstruction from those of standards B and 0, being set in a socket insaid slide, (where it can be moved up and down,) and is slitted into twoparts perpendicularly through and down the central line of said T, eachpart of said T then forming an F. Both of said F-shaped parts movingperpendicularly, as aforesaid, in said socket, are operated upon, whendesired, by the setscrew L, and may be adjusted at their proper desiredheights by means of said screw. One side of said standard A, of said i'-shape, is intended to give the proper gather of the axle, and

the other the proper set therefor, when said axle is submitted to orbrought in contact with the three standards. The standard A is the mostpeculiarand prominent new feature in this invention, as by means of it,operating in conjunction with the standards B and G, the proper gatherand true set for any axle may be reliably ascertained and determined. Atthe lower end of said 'I ["s in said slide D are two holes, as shown inFig. 2, into which are insertdd pins, which operate as stops to allowsaid F-parts to be raised in the slide, s o that the two parts formingthe one standard will, when drawn up as far as said pins will allow, beof the exact height of standards B and G, the three then forming astraight-edge, being in a direct line one with the other.

Having thus stated the nature of my invention, what I claim is- 1. Thestandard A, arranged substantially as described, for the purposeintended.

2. The standard A, provided with the slide D, in combination with thestandards B and 0, provided, respectively, with the slides E and F,arranged and operating substantially as shown and described.
